Jaw extension bodies are essential components in workholding operations in various industrial applications.
They are specifically designed to be compatible with the 30, 29 and 60 series of jaws, providing adequate extension to facilitate clamping and handling of parts during machining and assembly processes.
Manufactured from 20MnCr5 case-hardened steel, these extensions have been subjected to a quenching process until reaching a hardness of 60HRC, which gives them excellent wear resistance and a long useful life.
In addition, its reversible design, with three keyways on each side, allows up to six different clamping positions on the machine, providing great versatility and adaptability to the specific needs of the job.
It should be noted that these extensions are not guided, so they are not compatible with jaws that require guidance.

Recommendations for use:
Verify compatibility with jaw series prior to installation to ensure proper mounting.
Use reversible keyways to maximize clamping options and adaptability on the machine.
Avoid using these extensions with jaws that require guidance, as they are not designed for this purpose.
Ensure a firm and stable fit when mounting them on the machine, avoiding looseness that may affect accuracy.
Regularly inspect lashing surfaces for signs of wear or damage and replace if necessary.

Maintenance recommendations:
Periodically clean the extensions to eliminate machining residues that could compromise their operation.
Lubricate mating surfaces regularly to prevent corrosion and premature wear.
Store extensions in a dry and protected place when not in use, avoiding exposure to corrosive environments that can deteriorate the steel.
